Electromagnetic interaction
The force that electrically charged particles feel through electromagnetic fields, is called the electromagnetic interaction.
Explanation
The electromagnetic interaction is one of the 4 fundamental forces of nature. Light and other electromagnetic waves are a form of quantized, self-propagating oscillatory electromagnetic field disturbances called photons. Different frequencies of oscillation give rise to the different forms of electromagnetic radiation, from radio waves at the lowest frequencies, to visible light at intermediate frequencies, to gamma rays at the highest frequencies.
The special theory of relativity describes that electromagnetic radiation does not need a medium.
HistoryDanish physicist Hans Christian Ørsted discovered a correlation of electricity and magnetism in 1820. |
